Extensible Data Notation (EDN) is a format for serializing data.
The notation is used internally by Clojure to represent programs. It is also
used as a data transfer format like JSON. Though it is more commonly used in
Clojure, there are implementations of EDN for many other languages.
EDN is a subset of the syntax used by Clojure. Reading data defined by EDN is
safer than that defined by the full Clojure syntax, especially from untrusted
sources. EDN is restricted to data, no code. It is similar in intent to JSON.
Though it is more commonly used in Clojure, there are implementations of EDN
for many other languages.
The main benefit of EDN over JSON and YAML is that it is extensible. We
will see how it is extended later on.
